| # A test for a bug found by GraphicsFuzz. |
| |
| # Short description: A fragment shader with wrong color write in false if |
| |
| # The test passes because the shader always writes color red. |
| # Wrong color mix and write is inside a false if statement. |
| |
| SHADER vertex variant_vertex_shader PASSTHROUGH |
| |
| # variant_fragment_shader is derived from the following GLSL: |
| # #version 310 es |
| # precision highp float; |
| # |
| # precision highp int; |
| # |
| # layout(location = 0) out vec4 _GLF_color; |
| # |
| # layout(set = 0, binding = 0) uniform buf0 |
| # { |
| # vec2 injectionSwitch; |
| # }; |
| # |
| # void main() |
| # { |
| # float height; |
| # height = 256.0; |
| # |
| # if (injectionSwitch.y < 0.0) // always false |
| # { |
| # _GLF_color = mix(vec4(30.18, 8840.7235, 469.970, 18.24), vec4(9.9, 0.1, 1169.5387, 55.79), vec4(7612.9451, 797.011, height, 9.0)); |
| # } |
| # |
| # _GLF_color = vec4(1.0, 0.0, 0.0, 1.0); // Write color red |
